RUMED Germinator S 120 Jacobsen Method in Incubators, Drying Cabinets

RUMED Germinator S 120 Jacobsen Method
Ideally applicable for systematic ISTA compliant seed tests

From sample division over purity examination up to determination of germination - RUMED Germinators are the professional alternative to cooled incubators, wherever high reproducibility of the results is required.

The Jacobsen Method (Models S 120 and S 180)
The Jacobsen germinator mainly consists of a germination plate being temperature-conditioned by means of the water basin below. The water bath is equipped with an automatic temperature control.

The germination spirals being equipped with a paper wick and a paper substrate are placed on the germination plate. The wick is being led through slots in the germination plate and reaches into the water bath below, thus supplying the required humidity and the desired temperature to the paper substrate. The circular filter papers are covered with a transparent cover dome to provide the air humidity being required for the germination. A little hole in the upper end of that dome ensures sufficient supply of fresh air and minimum evaporation at the same time.

Units being executed with active cooling allow day-night temperature alternation, as well as any temperature profile.
